AI Technical Summary
Fingerprint locks easily leave fingerprint traces during fingerprint verification, which thieves can use to commit theft, thus reducing security.
The system uses a fingerprint ball combined with gesture recognition. As the fingerprint ball rolls, it moves a displacement plate and a sensor to record gesture information, which is then compared with information in a database module. This information is then combined with the fingerprint recognition module to unlock the device. Additionally, a cleaning wipe is applied to the surface of the fingerprint ball to remove fingerprints.
This improves the security of fingerprint locks, preventing thieves from extracting complete fingerprints from fingerprint traces, thus enhancing overall security.
